Hungry Hearts A young married couple in New York City engage in a fateful struggle over the life of their newborn child, in this eerie, claustrophobic suspense drama from Italian director Saverio Costanzo. Adam Driver stars.

The Cobbler THE COBBLER is a warm and character-driven comedy that plays to the strengths of Adam Sandler’s and Thomas McCarthy’s most commercial successes. Sandler plays a 4th generation shoe-maker who discovers a magical sewing machine in his father’s basement that allows him to transform into other people by wearing their shoes. Similar in theme to Tom Hanks’ BIG, TRADING PLACES, and 13 GOING ON 30, THE COBBLER provides the perfect vehicle for Sandler to exhibit his endearing and selfless boyish charm, taking him on a voyage of self-discovery and learning the importance of family via the magic of “walking a mile in another man’s shoes.” A journey that results not only in changing himself, but the world around him.

One Song Oscar® winner Anne Hathaway (INTERSTELLAR, LES MISERABLES) stars as Franny in SONG ONE, a romantic drama set against the backdrop of Brooklyn’s vibrant modern-folk music scene. After Franny’s musician brother Henry (Ben Rosenfield, BOARDWALK EMPIRE) is injured and hospitalized in a coma following a car accident, Franny returns home after a long estrangement and begins to use his notebook as a guide to how his life has evolved in her absence. Franny seeks out the musicians and artists Henry loved, in the course of her journey meeting James Forester (Johnny Flynn), his musical idol, whose success and fame belie a shy and private man. As a strong romantic connection develops between Franny and James, the question becomes if love can bloom even under the most adverse circumstances.

Realizing that the company can operate with one fewer employee, management tells Sandra she is to be let go. After learning that her co-workers will vote to decide her fate on Monday morning, Sandra races against time over the course of the weekend, often with the help of her husband, to convince each of her fellow employees to sacrifice their much-needed bonuses so she can keep her job.
